The long-time resident female at this nest is Spirit, banded black/green 93/E, born in 2004 at the Hilliard Road Bridge nest in the Cleveland, Ohio area. She is a daughter of the great pair Buckeye and Hillary. Now eleven years old, she is the only survivor of the four chicks born in 2004. Turbo was found dead shortly after fledging; Pulse was not seen for three years, until he turned up in 2007 at the Pittsburgh Cathedral of Learning nest. He was killed in a territorial battle by Erie, the resident male. The other female, Mystic, is also gone.
The resident male at this nest has been Roger, who is unbanded. However, in the fall of last year, Roger disappeared. He was replaced by Éole (Aeolus in English, named for the Greek ruler of the winds). Éole is a son of Spirit and Roger.
Earlier in this breeding season, Éole lost a territorial battle with an unbanded male. Spirit was just starting to lay her eggs; Éole is the father of the first egg and quite possibly the second also. The new male is the father of the other two.
It was not known at first what happened to Éole, but the good news is that he is alive and well. He has been seen and identified at the other nest in the area, on the incinerator building, with a new mate.
As happened at de Mortel, the new male did not incubate the eggs or bring food. Spirit has been caring for the eggs on her own. She did train the new male to start bringing her food and leaving it close by. He has been named Arthurin.
The eggs are due to begin hatching this weekend.
